Abstract

La présente invention concerne un procédé qui utilise des orifices capillaires dans une préforme en verre pour le positionnement précis des fibres optiques lors de la fabrication d'un coupleur. La préforme en verre est de préférence cylindrique et des orifices capillaires longitudinaux sont formés dans celle-ci dans un motif voulu. Des fibres optiques sont insérées dans les orifices et la préforme en verre est chauffée et étirée dans sa section centrale de manière à ce que les fibres, dont le revêtement a été retiré, entrent en contact et soient soudées avec la préforme en verre dans cette section effilée. Puis la section effilée est clivée afin de former une extrémité d'accouplement qui est épissée avec une autre fibre pour former le coupleur.
